19 Claims.

My invention relates 'to shoe marking machines, and particularly to a machine adapted for shoe upper back seam heightmarking.

,In the lasting of shoes there has been no definite method by which the operator can know exactly at what point, along the back seam particularly, he desires to turn the shoe upper over totack it to the last. Ordinarily the, operator gauges by eye, and estimates the desiredheight ofthe back seam of the upper, and then turns over-what he considers is the proper amount and tacks the turned over bottom edge of the upper to the last. i

. Without some definite mark on the shoe upper along the back seam either to indicatexthe desired height ofthe back seam or the desired amount 'to be turned over, irregularities in workmanship often result.

It is the object of my invention to provide a marking machine provided with means by which the operator can definitely indicate the material which he desires to turn over and tack to the last. It is a further object of my invention to provide a support for the shoe upper along the back seam, and to provide gauging and marking instrumentalities in which the marking device is so constructed and arranged that it will follow the lateral contour of the shoe upper.

In a machine of this type it is further my object to provide an adjustable marking device which canbe set for a desired thickness of shoe upper-so that the upper will not be injured by too deepor non-uniform marking and will yet be so thoroughly marked that an operator can easily observe the line on which he desires to turn over the lower edge of, the upper and secure it to the last. V

4O The above objects andother objects to which reference will be made in the ensuing disclosure, I accomplish by that certain combination and arrangement of parts of which I have illustrated a preferred embodiment, with several modifications indicating various ways in which the dimensions of the turned over part of the upper which is to be secured to the last may be indicated. 1 50 Referring to the drawings2 Figure 1 is a front elevation 7, from the pad end showing a preierredconstruction' of marking machine with the marker in mid position.

showing a modified type The machine is ordinarily mounted on a suitable tableor standardl and is composed of a frame having 'a base portion 2," with an elevated column 3; inwhich is rotatably mounted a shaft 4. A crank' armfi may be suitably connected to a rodfi extending below the machine and adapted to be operated by any suitable means, as byfa foot treadle 1, pivoted at "lot on l'JfiB'j'TfiOOl lb 'asdiag'rammatically shown in Figure The'shaft 4 may be lubricated by means of an oil cup 8.

On the end of the shaft oppositethe-crankfil have shown themarking arm 9, which is charmeled out as indicated at and in the channel a slider II is urged downwardly by means of a spring 12/ Within the channeled portion ID Ihave shown a block 13, andthe slider H has at its upper end a rod 14 which passes through, the block l3. Av

cover plate l5, which may be secured to the arm 9 with screws 15', encloses the slider H and limits it to an up and downreciprocating movement. The slider ll hasarms ll between which is journaled a marking disc [8.

has an extension l9, arid" The slider a thumbscrew 2i! in dotted lines at 24 in Fig ure 2, has a shaft portion 25 which extends through a hole in the base 2 and whichmay' be secured in a desired adjusted position with a lock screw 26. A gauge bar 21, having a flanged end 28, slides under a plate 29 having a slot 29 within a channeled portion of a block 30 which plate and block are secured to the base 2 as by means of screws.

For moving the gauge bar '21 to a desired position I have provided a shifting arm 3| pivoted as indicated at'32.- The arm 3! has an extension with a slot 33;" and a block 3 is secured to the arm ZT by a screw 35. This block34'is fsh'orter than slots 29' and33. The machine has graduations 36, and the handle member has a sharp edge 3 these graduations. It will be obvious that'when I which rides over the handle .7 3| is moved counterclockwise, as shown in the plan View in Figure 3, the flanged end 28 of the gauge is adv shoe upper support- :23.

anced towards the For inking the marking disc and supplying a constantly changing marking surface on the pad I have mounted, a circular pad 38 on a spindle 39. The spindle 39 is journaled in a boss 40 which forms part of a member having a spindle 42 journaled in a boss 43. The shaft 42 may be secured in desired adjusted position in the boss by means :of a set'screw 14. A :block 45 is secured to the spindle member 42 inclining to the rear of the machine and also toward the horn 23, and on this block 45 a pivoted pawl 46 is mounted, correspondingly inclined. The pawl has a tooth 41 which engages the ratchet teeth 48 of the circular member :carrying the pad. A spring 48 returns the pawl to its normal position against stop pin 50a. The end 50 of the pawl opposite the pawl .tooth -is engaged by a rocker 5i pivoted in the pedestal as indicated at 52. The rocker 5|, has an upwardly extending arm 53 which with the movement of the arm 9 across the path and across the shoe upper, is engaged, to rock the rocker 5| and operate pawl 46, by a rod 54 which extends from the boss 55 of the .arm -9. The booked and of rocker arm 53 limits the movement of the arm 9. A locking pawl 56 pivoted on the block 45 and affected by the spring 51, prevents the ratchet 4Ba from rotating in a nonfeeding direction, and as the pad is rotated by pawl 46 under action of rocker 51, .a constantly renewed inking surface is provided for the inking disc.

In the example of .the .machine shown .in Figures 1 to 3,,the upper 24 is positioned on the horn along the .top curved surface thereof, and the upper edge of the back seam placed against the sfianged end 28 of the gauge. The disc marker will then indicate a predetermined height of back seam, and if the operator "of the machine places the marked line :at the bottom edge of the last and turns the upper over on the line, a very accurate vregulation of the height of the back seam may be obtained.

.As a modified type of arrangement in Figure 4 I have indicated details of the machine in which, instead :of gauging the height .of the back seam, I provide means for gauging the amount of the upper which is to be turned over and lasted. The horn 23a has a contoured :support and .a flattened surface 58 'on which I have shown .a .slidably adjustable gauge 59 .having a. lot BB therein which enables the flanged end .6! of the gauge to be moved to a position in which it may be set by means of the set screw 62, which .has a shank 63 which engages a threaded hole in the horn. In using the modification shown in Figure 4 a mark may be placed on :the upper which corresponds to the mark provided with the other method of gauging, but in this instance the gauged dimension will be the amount of the upper to be turned over in the lasting.

In Figure 4 I have :further indicated a heating unit 64 which may be mounted on the arm 9 and by which the marking instrument may be heated if desired so as to form a more distinct line to indicate the line at which the upper is to be turned over in the lasting operation or to use marking or impression material requiring :the use 'of :heat for proper impressions.

A particular feature of my machine .of great importance is the resilient momiting for the slider carrying "the marking :device which enables the marking instrument ;not only to mark a line along the back seam, but to follow the contour for any desired distance, which enables me to mark a shoe upper with a line which will be easy to follow in the lasting operation, and in the application of which there will be no tendency to mar the shoe upper.
